The uniform energy factor for residential and certain commercial water heaters refers to its efficiency when run under standardized conditions for a 24 hour period.

Water heater energy factor calculator.

Energy factor 0 92 electric 0 61 gas energy cost 0 06 per kwh 60 per therm. An energy factor is a metric used in the united states to compare the energy conversion efficiency of residential appliances and equipment. Using the doe test procedure for calculations a fifty gallon electric resistance storage water heater with an energy factor of 0 95 would consume 4 622 kilowatt hours per year see table 1 on page nine for figures. Expressed as a decimal the uniform energy factor is determined by running a department of energy specified simulated use test sut.

The energy factor is currently used for rating the efficiency of water heaters dishwashers clothes washers and clothes dryers. To calculate a water heater s energy factor you take the amount of energy the water heater puts to use and divide it by the total amount of energy that goes into powering the unit. Hi larry the energy that is used to heat water from 40 degrees to 60 is the same amount that is lost when the water cools down from 60 to 40 only changed sign. Typical fifty gallon electric resistance storage water heaters have energy factors that range from 0 904 to 0 95.

The energy factor is based on the amount of hot water produced per unit of fuel consumed per day. The water heaters themselves haven t changed but the way we calculate the ratings and other facts and figures associated with them is different. Use the energy factor to determine the energy efficiency of a storage tankless or demand type water heater or heat pump water heater. Electric water heaters typically have energy factors between 0 75 and 0 95.

The higher the energy factor of a water heater the more efficient it is. To determine btu lost can i use the water heating energy calculator only backwards. In fact uef provides a more consistent and accurate way to measure energy efficiency performance in water heaters across all national brands. The term is used by the united states department of energy to develop and enforce minimum energy conservation standards under.

Quantity of water heaters to be purchased unit s 1 unit see assumptions for various daily water use totals. The energy factor ef indicates a water heater s overall energy efficiency based on the amount of hot water produced per unit of fuel consumed over a typical day. Next you can adjust your current water heater s energy factor as well as the energy factor of your new water heater. The comparison assumes a storage tank water heater as the input type.

A water heater s energy factor ef is a measure of useful energy coming out of the water heater divided by the amount of energy going in.
